This was a failure to test properly on my part, sorry about that.
After some debugging today I've figured out at least what the problem is;
LD_PRELOAD was in the restored environment (BB_ORIGENV) in dylan whereas in
master it was not, due to the way pseudo is used there, which explains why the
change you mentioned worked in master and not in dylan. I have just sent a
patch for dylan to this list to exclude LD_PRELOAD from the environment which
fixes the problem in my testing here.
Cheers,
Paul
